301 test 2 Flashcards
what can nutrition effect?
tissue integrity, sensory perception, and elimination
what can effect nutrition
hormonal regulation, elimination, glucose regulation, and sensory perception
people with burns are at risk for
hypovolemic shock
purpose of nutritional assessment
identify individuals who are malnourished/dehydrated or are at risk for development of calorie and liquid malnourishment.
what lab do we look at to assess nutrition
total protein= prealbumin, albumin, and globulin
normal albumin
3.5-5 gdL
what does albumin lab measure
circulating protein. can be impacted by fluid status and liver function
how long will it take to see fluctuations of albumin
3-4 weeks
prealbumin normal levels
15-36 mg/dL
what does prealbumin reflect
protein and calorie intake for the previous 2-3 days
normal levels of blood glucose
70-105 mg/dL
what does blood glucose reflect
carbohydrate metabolism
what can hgb/hct indicate in labs
can indicate anemia caused by low iron, folate and vitamin B12
what does the lipid profile show
reflects lipid metabolism
what can BUN/creatine ratio and urine specific gravity be used for?
to determine hydration status
normal range of BUN/ creatine ratio
20:1
Hemoglobin A1C
glucose levels over long period of time
what topics are included in present health history for nutrition assessment
chronic illness, medications, weight changes, food intolerances, street drugs or alcohol, problems obtaining eating food, weight concerns
what do alcohol and street drugs do to your nutrition
decrease nutritional absorption
what measures can be taken to correct weight concerns
diet and exercise modifications and surgery
methods of obtaining a diet history
24 hour recall, typical food intake, food diary, comprehensive diet history
nutritional exam includes
anthropometric measurements, inspections of skin, hair, and nails, inspections of eyes, inspection and palpation of the extremities bilaterally
BMI
body mass index, estimate of total body fat
triceps skin fold
evaluate subcutaneous fat stores
mid-arm muscle circumference
evaluate muscle reserve
how do you calculate BMI with inches and pounds
((weight in pounds/(height in inches x height inches)) X 703
BMI underweight
below 18.5
BMI normal
18.5-24.9
BMI overweight
25-29.9
BMI obesity class 1
30-34.9
BMI obesity class 2
35-39.9
BMI morbid obesity
40 and greater
BMI chart does not work on individuals who are
below 5 feet
BMI does not differentiate between
fat and muscle tissue
what happens with muscle mass in elderly
they tend to lose it
what should you add to BMI to increase predictability for health risk
waist circumference
calculate percent change in weight
current body weight/usual body weight X 100
calculate waist to hip ratio
pear shape vs apple shape
DBW
desirable body weight
normal DBW
(desirable body weight) normal is 90-110%
what happens with nutrition as you get older
physical limitations, decreased taste and appetite, muscle tone and mass decrease, loss of subcutaneous fat, become more salt sensitive, fat is redistributed
assessing hydration status
weight, skin turgor, pitting edema, skin moisture, tongue,lung sounds, blood pressure, urine output
malnutrition can be confused with what other diseases
anemia, hyper or hypothyroidism, hepatic disease, alcoholism, cancer, depression
obesity related conditions
obesity related conditions include heart disease, CVA, DM type 2 and certain types of cancer
what portion of America is obese
1/3
estimated annual cost of medical cost towards obesity
147 billion
obesity risk factors
sedentary lifestyle, high fat diet, genetics, ethnicity/race, female, age
reasons for undernutrition
acute illness, chronic disease, extreme age, alcohol abuse, depression, limited knowledge, physical inability, eating disorder, poverty, lifestyle
enteral feeding
tube feeding provided through a tube inserted into the nose to stomach, small-intestine, or gastrostomy
parenteral nutrition
when GI tract can no longer be used for digestion. can be IV fluids with dextrose or total parenteral nutrition
parenteral nutrition has high risk for
infection
PEG
percutaneous endoscopic gastronomy tubes
signs of fluid overload
weight gain, pitting edema, visible neck veins, crackling lung sounds, elevated pulse rate and blood pressure, SOB
new food guidance system in US
choose my plate includes 5 food groups. make half your plate fruits and vegetables and half your plate grains and protein
peritoneum
serous membrane forming protective cover of the abdominal cavity
peritoneum divided into what 2 layers
parietal and visceral
peritoneal cavity
space between the parietal and visceral layers, contains small amount of serous fluid to reduce friction
alimentary tract
27 feet long. ingest, digest, absorb nutrients, electrolytes, and water, and excrete waste product
what parts does the alimentary tract include
esophagus, stomach, small intestine, and large intestine
esophagus ph
6-8
stomach ph
2-4
chyme
breakdown and conversion of carbs, proteins, and emulsified fat that is liquified
what does chyme consist of?
peptones, amino acids, fatty acids, and glycerol
small intestine
largest section of GI tract includes duodenum, jejunum, and ileum
large intestine
about 5 feet. includes cecum, colon, rectum, and anal canal
liver functions
bile production, secretion to emulsify fat, transfer bilirubin, metabolism of proteins, carbohydrates, and fats, storage of glucose in form of glycogen, production of clotting factors and fibrinogen for coagulation, synthesis of plasma proteins, detoxification of substances, and storage of minerals and vitamins
plasma proteins
albumin and globulin
gallbladder
stores bile produced by liver and ducts drain bile into duodenum
bile in feces cause
the brown color
pancreas
produces endocrine secretions and exocrine secretions
endocrine secretions
insulin, glucagon, somatostatin, and gastrin
exocrine secretions
bicarbonate, pancreatic enzymes
spleen
filters antigens from the blood, important in response to systemic infections, activation of B and T lymphocytes, stores erythrocytes and platelets
